Title: Dynamic Latent Feature Learning and Troubleshooting of 
Manufacturing Processes 

Abstract: Sustained and unsettled dynamics in real-time data from manufacturing processes often indicate troubled control performance or equipment malfunctioning. In this talk, we present a latent dynamic feature extraction framework to achieve simultaneously dimension reduction and latent dynamic modeling.  The dynamic latent features are enforced to be orthogonal and used for troubleshooting process anomalies. Composite loadings and weights are given to analyze root causes and contributions to a dynamic feature of interest. The dynamic embedded feature analytics (DELFA) approach to process troubleshooting is introduced and demonstrated on several industrial manufacturing processes with great successes.
